Abstract (en)

The mower (20) has at least two independently driven wheels (52,54) that are each capable of bi-directional rotation. The at least two wheels (52,54) are independently driven so that operation of the at least two wheels (52,54) causes the at least two wheels (52,54) to independently rotate which propels and steers the mower (20). A microprocessor controls the operation of the at least two wheels (52,54) in accordance with signals received by the microprocessor. The mower (20) has at least one controller (66). The at least one controller (66) sends signals to the microprocessor that the microprocessor uses to control the operation of the at least two wheels (52,54). The operation of the at least one controller (66) causes the at least two wheels (52,54) to propel and steer the mower. <IMAGE>
